Determination of volume status i.e. dehydration, edema, ascites should be carried out.[29] Patients with clinical signs of volume depletion (e.g. orthostatic decreases in blood pressure and increases in pulse rate, dry mucus membranes, decreased skin turgor) should be considered hypovolemic. When available, direct hemodynamic measurements can provide corroboration of the clinical impression.

Overview

Patients with [disease name] usually appear [general appearance]. Physical examination of patients with [disease name] is usually remarkable for [finding 1], [finding 2], and [finding 3].

OR

Common physical examination findings of [disease name] include [finding 1], [finding 2], and [finding 3].

OR

The presence of [finding(s)] on physical examination is diagnostic of [disease name].

OR

The presence of [finding(s)] on physical examination is highly suggestive of [disease name].

Physical Examination

  • Nausea and malaise are the earliest signs of hyponatremia.
Classification Clinical signs
Hypervolemic

hyponatremia

Peripheral edema, ascites, pulmonary edema, raised JVP,clinical signs of underlying causes
Euvolemic hyponatremia Clinical signs of underlying causes
Hypovolemic hyponatremia Dry mucous membrane, decreased skin turgor, hypotension (orthostatic), tachycardia
  • Look for signs of hypothyroidism
